DAHANCA Initiates Head and Neck Cancer Study with Genmab's HuMax-EGFr


Summary:  Genmab announces the initiation of a Phase III study of HuMax-EGFr to 
treat head and neck cancer in cooperation with DAHANCA.                         

Copenhagen, Denmark; September 13, 2007 - Genmab A/S (OMX: GEN) announced today 
the initiation of a Phase III study of HuMax-EGFr(TM) (zalutumumab) to treat    
head and neck cancer in cooperation with the Danish Head and Neck Cancer Group  
(DAHANCA).  The study will include approximately 600 previously untreated head  
and neck cancer patients to assess whether concomitant therapy with HuMax-EGFr  
can improve the efficacy of primary curative radiotherapy.                      

“We are excited for DAHANCA to begin the largest HuMax-EGFr trial to date,” said
Lisa N. Drakeman, Ph.D., Chief Executive Officer of Genmab.  “We hope that      
HuMax-EGFr provides additional benefit to head and neck cancer patients         
receiving radiotherapy.”                                                        

About the trial                                                                 
Patients in the study will be randomized to treatment with radiotherapy or      
HuMax-EGFr plus radiotherapy.  All patients will receive treatment with         
accelerated radiotherapy plus nimorazole and may also receive cisplatin         
chemotherapy.  Patients receiving HuMax-EGFr will receive six weekly doses of 8 
mg/kg of HuMax-EGFr.  Patients will be followed for at least 5 years and will be
clinically evaluated at months 2, 5, 8 and 12 after completion of treatment.    
Evaluations will continue every 4 months in the second year and every 6 months  
the third and fourth year and once a year thereafter.                           

The objective of the study is to determine the efficacy of HuMax-EGFr in        
combination with radiotherapy in treating patients with squamous cell carcinoma 
of the head and neck.  The primary endpoint is loco-regional control and        
secondary endpoints are overall survival, disease free survival and acute and   
late side effects.                                                              

About cancers of the head and neck                                              
Head and neck cancers may affect the mouth, nasal cavities, sinuses, larynx and 
pharynx. Most are squamous carcinomas but others include lymphoepithelioma and  
lymphoma.  Head and neck cancers account for 3 % of all cancers in the U.S.,    
with 40,000-60,000 cases diagnosed and 12,000 deaths annually. Worldwide        
incidence is about half a million with nearly 250,000 deaths.
